Title: Innovations by Wate Thewis Bakker

Introduction

Wate Thewis Bakker is an accomplished inventor based in Anne Arundel County, MD. He holds three patents that showcase his expertise in the field of refractory materials. His innovative approaches have significantly contributed to advancements in the manufacturing processes of refractories used in various industrial applications.

Latest Patents

One of Bakker's notable patents is for an improved periclase refractory and its method of manufacture. This invention involves using an alkyd resin binder to temper and press periclase grains into refractory shapes, such as bricks. The pressed shapes undergo drying and firing, followed by vacuum impregnation with molten pitch, making them suitable for lining basic oxygen steelmaking furnaces. The resulting refractory bricks exhibit a remarkable modulus of rupture at 1482°C, ranging from 3000 to 4000 p.s.i. Additionally, Bakker's method enhances the green strength of the alkyd resin bonded bricks by incorporating a strong organic acid prior to mixing with periclase grains, achieving a green strength between 30 and 40 p.s.i.

Another significant patent by Bakker focuses on an improved alumina or alumino-silicate refractory for aluminum-melting furnaces. This invention includes the addition of 0.5 to 30% by weight of BaSO4, which effectively eliminates metal penetration and reduces dross and metal adherence in phosphate-bonded or phosphate-free mixes, bricks, mortars, or castables.
